    Mapping for how the ref can be named in for example the <code>@Library</code>.<br/>
    Example: test-@{1} <br/>
    Where @{1} replaces the first wildcard in the ref when discovered.
</p>
<p>
    By default it will be "namespace_before_wildcard-@{1}". E.g. if ref is "test/*/merged" the default mapping would be
    "test-@{1}".
